April Fool’s day (the beginning of a new April month) was sunny, quite chilly and windy early but diminishing as the day progressed. A friend of mine about 10 miles north of me in the Damascus area reported a few snow flakes falling around 0830 to document how cold it was. Low temps around 30° in the early AM only rose up to the mid 40s by mid-afternoon.  Temps didn’t quite drop as much as on Sunday (greater wind advection), but were still in the upper 30s by midnight. 

The maximum temperature was 46.3° at 1603.

The minimum temperature was 30.2° at 0704.

The dew point temperatures ranged from a low of 15° @ 0001 up to a high of 23° @ 0839.

The relative humidity values ranged from a high of 66% @ 0714 down to a low of 29% @ 1637.

The barometric pressure ranged from a low of 30.17″ @ 0001 up to a high of 30.39″ @ 1105.

Monday had no precipitation. My March monthly total finished at 4.67″ with my year-to-date total at 11.69″.

No snow/sleet fell on Monday. My March total snowfall wound up with 2.5″ with the seasonal total at 26.8″. This will be the last report of the season for snowfall till late next fall unless we get a surprise snow sometime this month.  

My current online data (except for rainfall/snowfall – use the cocorahs link shown below for that dataset) is showing regularly on Weather Underground. My data is posted there every 5 minutes. My ID is KMDROCKV200 and my station is called “Gardens of Traville.” Data is online, normally just about in real-time now as it is being updated on a 5 minute interval. The web address for my data on weather underground is:
https://www.wunderground.com/personal-weather-station/dashboard?ID=KMDROCKV200

I contribute my precipitation data daily to CoCoRaHS as Rockville 2.8 WNW, Station ID MD-MG-115 on https://www.cocorahs.org/

Please remember that my Weather Underground precipitation data reflects what is recorded automatically through the tipping bucket VP2 gauge, just as it does on WxLink 2.0. The tipping bucket has been producing erratic values at times so should not be used except for general precipitation timing.

I actually use the data I post to CoCoRaHS from my 4 inch CoCoRaHS gauge I read manually as my “official” precipitation total each day.

Expect it to be partly to mostly cloudy on Tuesday with rain showers later on in the afternoon and evening and a bit milder, with high temps in the upper 40s and lows in the mid 30s. A coastal LOW has been developing off the SE coast and is moving up and strengthening as it goes. Our later day rain will be caused by the western fringe of this storm. 

Wednesday should be mostly sunny and milder, with highs in the mid 60s and lows in the low 40s.

Thursday should be mostly cloudy and mild, with highs in the mid 60s and lows in the mid 40s.

Friday looks to be cloudy and cooler, with temps in the 50s and rain expected. The weekend looks milder but remaining cloudy, with highs around 70° and lows in the 50° – 55° range. 

Midnight Monday night found the temperature to be 39.2°, relative humidity 48%, pressure steady at 30.38″ and the dew point a low 21.1° under clear skies.

Currently at 0715 the temperature is 33.3° under mostly clear skies but with scattered high clouds and a few contrails,  relative humidity at 79%, barometric pressure steady at 30.38″, and the dew point at 28°.

Good morning from the snowless walrus on this clear, chilly, dry Tuesday.

With peak bloom of the famous downtown Washington DC Cherry Trees in the Tidal Basin occurring this week, trees and shrubs around here are looking more springlike also. Today’s attached image file is a picture posted on FACEBOOK by my photo-journalist weather enthusiast friend Jim Schuyler of the blooming joshino cherry trees in downtown DC at the aforementioned Tidal Basin backdropped by the famous Washington Monument taken Monday afternoon. Thanks so much Jim!!!
